Comment on Show HN: Gravity – Interactive solar-system simulator, from Newton to Einstein

Comments

Really cool project! I always struggled to understand the motion of the planets looking at 2D images in textbooks. So I really enjoyed the ability to click and drag to explore the motion of the planets in 3D. I think it helps me build a more accurate mental modal of our solar system.

I also loved the music and narration, I'm curious what you used to create the narration? I noticed the narrator seemed to struggle with numbers sometimes, for example on step 1: "The Sun is ~333 000× heavier" The ~333 000× portion does not seem to be read properly. Not sure if that's only a problem I am experiencing on my browser though.

I'm going to fix this soon. I've used elevenlabs for both narrator and music
